CHARLES M. BURGESS, OF NEIV BRITAIN, CONNECTICUT, ASSIGNOR TO THERUSSELL & ERWIN MANUFACTURING COMPANY, OF SAME PLACE.

SHEET-METAL LATCH-KEEPER.

SPECIFICATION forming part of Letters Patent No. 421,381, dated February18, 1890.

Serial No. 336,017. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES M. BURGESS, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inSheet-Metal Latch-Keepers, of which the following is a specification.

My invention relates to improvements in sheet-metal latch-keepers; andthe objects of my improvement are simplicity of construc tion andefflciency in the finished article.

In the accompanying drawings, Figure 1 is a side elevation of my keeper;Fig. 2, a front elevation; Fig. '3, a transverse section on line x 00 ofFig. 2; Fig. at, a plan view of the blank from which said keeper isformed; Fig. 5, a side elevation of my keeper in a slightly-differentform; Fig. 6, a front elevation of the same, and Fig. 7 a plan view ofthe blank from which said keeper is formed.

The keeper is designed for surface looks or latches, the same beingknown a as rimlatches.

I form my keeper of a box-like bodyA and a rearwardly-projecting flangeB. The edges of the sheet metal at the back or openside of the box isdesigned to rest against the front surface of the casing or door-frame,while the flange is designed to rest against one side thereof. I formthis keeper from a flat sheetmetal blank and perforate the body to formthe screw-holes 8 to receive the screws that extend into the front faceof the door-frame or casing, and with one or more screw-holes 9 toreceive a screw or screws that extend into the door-jamb or casing atright angles to the aforesaid screws. The flange B in the blank is of awidth equal to the depth of the boxlike body and the rearward projectionof said flange. It is also provided with a mortise or mortises 10 inthat portion which in the finished keeper will form one side of saidbody portion. The blank is also provided at each flange 12,1hat formsthe side of the body opposite to that having the mortise or mortises.The blank is then struck in suitable dies to give the desired finish orornament to the front face and to bend the respective wings or flangesinto the proper form, as shown in Figs. 1, 2, and 3.

In Figs. 5, 6, and 7 the same constructionis followed, excepting thatangular corners are not cut out at the junction of the wings 11 and 12;but in lieu thereof the corners of the blank are rounded and the keeperwhen struck up is given more of an ornamental form, with corrugations orbeads 13 at the corners.

In addition to ornamentation, the swaging or striking up of the frontin. dies enables me to use much thinner metal than has heretofore beenemployed, and the form of my blank and keeper is such that its front isadapted to be so struck up. The flange B, although old of itself, is animportant feature in a keeper made of thin sheet metal, as it receivesthe thrust of the latch-bolt when the door is being closed, the force ofwhich is resisted by a screw or screws in said flange, therebypreventing the edges of the thin metal, which are seated upon the faceof the casing, from being forced into the wood.

I claim as my invention- The herein-described sheet-metal keeper,consisting of a box-like body portion and a rearwardly=projectingflange, all struck up from a single piece of sheet metal from a blankhaving wings or flanges at the sides and ends of the central portion,the edges of the metal at the open side of said body portion in thecomplete article being designed to rest upon the front face of thecasing or doorframe, substantially as described, and for the purposespecified.
